OSU Lime Bulletin for Western Oregon

OSU Western Oregon Lime Bulletin - August 2019 (pdf)

There have been some recent concerns regarding changes to buffer pH soil test methods being used by soil test labs serving Oregon. These changes may impact lime recommendations for many cropping systems in the Willamette Valley. We have developed a short 1-page bulletin which explains the situation, describes what is being worked on, and provides current OSU recommendations for liming in western Oregon.
